Adobe Systems announced Monday new versions of Photoshop and other key publishing and graphics products, but some of the biggest changes won't be in the applications.

The software maker's new product combines Photoshop, the InDesign page layout application and the Illustrator graphics application into the Adobe Creative Suite, a package that includes integrated tools intended to help make it easier to move work from one application or person to another. Chief among the new tools is Version Cue, a basic content management tool intended to improve the way workers share files for collaboration and review.

"The big difference here is that not only are all of the applications in the suite...being significantly upgraded, but the way in which they work together is unsurpassed and something we've never done before," Adobe CEO Bruce Chizen said. "The problems our customers are facing, in terms of managing content, are enormous," said Mark Hilton, Adobe's director of product management. "The vast majority of our customers are using multiple Adobe applications, so there are significant workflow issues we can address."
